I am working on a unit-aware arithmetic library for swi-prolog (1) modeled after the c++ mp-units library (2). Turns out prolog is really well suited for this because:

* of its ability to store unit system data as code

* unit conversion is an iterative deepening depth first search

* manipulating symbolic arithmetic is so easy

Unfortunately, it requires users to compile swi-prolog for source because the library is using some unreleased features. If anyone would like to test and report some feedback, I would be truly grateful !

I am a PhD student and for a while now I'm designing and developing a distributed network protocol that enables dynamic resource allocation across heterogeneous nodes, to which I called Rank. It's designed to handle computational, network, and temporal resources in fully distributed environments without central controllers, but that could also handle a centralized environment. Rank implements four core functions: dis…

Thank you so must for your interest! I am working on publishing results and trying to create a proper webpage to reference Rank and all the documentation. My goal is to open this project as an open-source project as soon as I can so that everyone is able to build their solutions out of it and also contribute to the project. I'll keep you posted on that!

After 10 years in defense tech, watching missile attacks in Ukraine and the Middle East made it clear how little most people really get about air defense. So I'm builiding this simulator which drops you into the operator’s seat. You can test out different scenarios and build an air defense network against various types of threats (stats from real world). Also have Ukraine, Israel-Iran scenarios. https://airdefense.de…

Really cool. Wish I could see more of the system log messages, that's the most interesting part to me.

Tangential: do you have insights into viability of mini automated anti-drone turrets? Something you'd place on a truck or pull out of a trench when needed? We already have drones with shotguns. I guess it's the automatic acquisition and targeting that's the difficult part, but just how difficult is that?

Working on a platform to host and share 3D Gaussian Splatting models.

The key goal is that the creators of 3DGS models can use Blurry as a powerful tool to build the 3D experience that is performant, simple, and aesthetically pleasant for end users (viewers).

3DGS models can be shared via a link or embedded on a website, notion, etc..

I made a film called "Searching For Kurosawa". This short documentary chronicles the story of Kawamura, a man who worked with legendary Japanese director Akira Kurosawa on the set of his opus "Ran". Kawamura was working in the BTS crew, but his footage got confiscated. It took almost 40 years to recover the footage and present that as his feature film. My film got screened at the Academy Award-qualifying Bali Interna…

funny, I was just dubbing some great edits of Kurosawa films in somebody else's film essay with some music I like.

Numpad: https://numpad.io/

It's a web-based notepad calculator, which means it's a notes app but it can evaluate inline calculations like

``` £300 in USD + 20%

09:00 to 18:30 - 45 minutes ```

I wrote the core of the calculator a few years ago, and I've just launched a big rewrite that supports

* document syncing * offline editing * markdown formatting * PDF and HTML exports * autocomplete * vim mode

Happy to hear feedback :)

I've built a cli tool to help extract content from webpages into markdown. This was an experiment to get used to a new workflow using claude-code and task-master.

It doesn't require an LLM or api keys to run so you can install and go. Hope it helps somebody:

  npm install -g url-to-markdown-cli-tool

PFAS Free Life: https://pfasfreelife.com

I’m trying to build a consolidated database of PFAS free products that make it easier for shoppers to find safe foods, cleaners, clothes, and other products families commonly use. The database shows not only the product, but the reason it’s considered pfas free; sometimes all you have to go on is the brands word, sometimes there is third party testing for pfas, sometimes there is a material issue justifying it. We tried to present it all for the consumer to easily decide. Users can search, or browse for products using categories.

The database is here: https://database.pfasfreelife.com/

C# playground (compiler explorer) which runs entirely in a browser (via WebAssembly). Started as an alternative to SharpLab which is not maintained anymore. But it can also do some other stuff that I wanted like downloading any compiler version, and compiling Razor. Recently I've added some "IntelliSense" features to improve the editing experience.
